1 PRECAUTIONS FOR DEVICES THAT USE R407C REFRIGERANT
Caution
Do not use the existing refrigerant piping.
•The old refrigerant and refrigerator oil in the existing piping contains a large amount of chlorine which may cause the refrigerator oil of the new unit to deteriorate.
Use refrigerant piping made of phosphorus deoxidized copper and copper alloy seamless pipes and tubes”. In addition, be sure that the inner and outer surfaces of the pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminant.
•Contaminants on the inside of the refrigerant piping may cause the refrigerant residual oil to deteriorate.
Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing. (Store elbows and other joints in a plastic bag.)
•If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
Use ester oil, ether oil or alkylbenzene (small
amount) as the refrigerator oil to coat flares and
flange connections.
•The refrigerator oil will degrade if it is mixed with a large amount of mineral oil.
Use liquid refrigerant to seal the system.
•If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance may drop.
Use a vacuum pump with a reverse flow check valve.
•The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate.
Do not use the following tools that have been used with conventional refrigerants.
(Gauge manifold, charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge, refrigerant recovery equipment)
•If the conventional refrigerant and refrigerator oil are mixed in the R407C, the refrigerant may deteriorated.
•If water is mixed in the R407C, the refrigerator oil may deteriorate.
•Since R407C does not contain any chlorine, gas leak detectors for conventional refrigerants will not react to it.
Do not use a charging cylinder.
•Using a charging cylinder may cause the refrigerant to deteriorate.
Be especially careful when managing the tools.
•If dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate.
If the refrigerant leaks, recover the refrigerant in the refrigerant cycle, then recharge the cycle with the specified amount of the liquid refrigerant indicated on the air conditioner.
•Since R407C is a nonazeotropic refrigerant, if additionally charged when the refrigerant leaked, the composition of the refrigerant in the refrigerant cycle will change and result in a drop in performance or abnormal stopping.
Do not use a refrigerant other than R407C.
•If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerator oil to deteriorate.
–3–
[1] Storage of Piping Material
(1) Storage location
Store the pipes to be used indoors. (Warehouse at site or owner’s warehouse)
Storing them outdoors may cause dirt, waste, or water to infiltrate.
(2) Pipe sealing before storage
Both ends of the pipes should be sealed until immediately before brazing.
Wrap elbows and T’s in plastic bags for storage.
*The new refrigerator oil is 10 times more hygroscopic than the conventional refrigerator oil (such as Suniso). Water infiltration in the refrigerant circuit may deteriorate the oil or cause a compressor failure. Piping materials must be stored with more care than with the conventional refrigerant pipes.
–4–
[2] Piping Machining
Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil to coat flange connections.
Use only the necessary minimum quantity of oil !
Reason :
1. The refrigerator oil used for the equipment is highly hygroscopic and may introduce water inside.
Notes :
•Introducing a great quantity of mineral oil into the refrigerant circuit may also cause a compressor failure.
•Do not use oils other than ester oil, ether oil or alkylbenzene.
–5–
[3] Brazing
No changes from the conventional method, but special care is required so that foreign matter (ie. oxide scale, water, dirt, etc.) does not enter the refrigerant circuit.
Example : Inner state of brazed section
When non-oxide brazing was not used |
When non-oxide brazing was used |
Items to be strictly observed :
1.Do not conduct refrigerant piping work outdoors on a rainy day.
2.Apply non-oxide brazing.
3.Use a brazing material (Bcup-3) which requires no flux when brazing between copper pipes or between a copper pipe and copper coupling.
4.If installed refrigerant pipes are not immediately connected to the equipment, then braze and seal both ends of them.
Reasons :
1.The new refrigerant oil is 10 times more hygroscopic than the conventional oil. The probability of a machine failure if water infiltrates is higher than with conventional refrigerant oil.
2.A flux generally contains chlorine. A residual flux in the refrigerant circuit may generate sludge.
Note :
•Commercially available antioxidants may have adverse effects on the equipment due to its residue, etc. When applying non-oxide brazing, use oxygen free nitrogen (OFN).
–6–
[4] Airtightness Test
No changes from the conventional method. Note that a refrigerant leakage detector for R22 cannot detect R407C
leakage.
Halide torch |
R22 leakage detector |
Items to be strictly observed :
1.Pressurize the equipment with nitrogen up to the design pressure and then judge the equipment’s airtightness, taking temperature variations into account.
2.When investigating leakage locations using a refrigerant, be sure to use R407C.
3.Ensure that R407C is in a liquid state when charging.
Reasons :
1.Use of oxygen as the pressurized gas may cause an explosion.
2.Charging with R407C gas will lead the composition of the remaining refrigerant in the cylinder to change and this refrigerant can then not be used.
Note :
•A leakage detector for R407C is sold commercially and it should be purchased.
[5]Vacuuming
1.Vacuum pump with check valve
A vacuum pump with a check valve is required to prevent the vacuum pump oil from flowing back into the refrigerant circuit when the vacuum pump power is turned off (power failure).
It is also possible to attach a check valve to the actual vacuum pump afterwards.
2.Standard degree of vacuum for the vacuum pump
Use a pump which reaches 0.5 Torr (500 MICRON) or below after 5 minutes of operation.
In addition, be sure to use a vacuum pump that has been properly maintained and oiled using the specified oil. If the vacuum pump is not properly maintained, the degree of vacuum may be too low.
3.Required accuracy of the vacuum gauge
Use a vacuum gauge that can measure up to 5 Torr. Do not use a general gauge manifold since it cannot measure a vacuum of 5 Torr.
4.Evacuating time
•Evacuate the equipment for 1 hour after –755 mmHg (5 Torr) has been reached.
•After envacuating, leave the equipment for 1 hour and make sure that the vacuum is not lost.
5.Operating procedure when the vacuum pump is stopped
In order to prevent a backflow of the vacuum pump oil, open the relief valve on the vacuum pump side or loosen the charge hose to drawn in air before stopping operation.
The same operating procedure should be used when using a vacuum pump with a check valve.
–7–
[6] Charging of Refrigerant
R407C must be in a liquid state when charging, because it is a non-azeotropic refrigerant.

Reasons :
1.R407C is a mixture of 3 refrigerants, each with a different evaporation temperature. Therefore, if the equipment is charged with R407C gas, then the refrigerant whose evaporation temperature is closest to the outside temperature is charged first while the rest of refrigerants remain in the cylinder.
Note :
•In the case of a cylinder with a syphon, liquid R407C is charged without turning the cylinder up side down. Check the type of cylinder before charging.
[7]Dryer
1.Replace the dryer when the refrigerant circuit is opened (Ex. Change the compressor, full gas leakage). Be sure to replace the dryer with a CITY MULTI Series Y (For use with R407C).
If any other product is used, the unit will be damaged.
2.Opening the refrigerant circuit after changing to a new dryer is less than 1 hour. The replacement of the dryer should be the last operation performed.
